His love of music and the intricacies of cryptanalysis
went hand in hand as the mathematical connection between the two is strong.

com)-- He is most vividly remembered for his work on cryptanalysis
during World War II, developing the so-called electro-mechanical Bombe used to determine the correct rotor and plugboard settings of the German Enigma encryptor to decrypt intercepted messages - a development said to have shortened the length of World War II by two years.
During the World War II, Alan Turing was heading a team responsible for German naval cryptanalysis
CHRISTOPHER SWENSON, MODERN CRYPTANALYSIS
Turing's utility as the brains of an important part of the wartime British cryptanalysis
operation run out of Bletchley Park kept him on the government's payroll and out of the hands of the law during the war.
Using cryptography for data security is adopted in many of the existing systems but they use only a single algorithm for encryption and decryption, which are vulnerable to attacks by cryptanalysts and are broken at some instance by one of the various cryptanalysis
techniques such as linear cryptanalysis
, n-gram analysis, meet in the middle attack, brute force attack, etc.
After a cryptanalysis
phase ranging over 4 years, stream ciphers were filtered in 3 phases by their performance and security.
These requirements are summarized by two questions: how secure is the generated keystream against cryptanalysis
attacks and how strong is the generated keystream statistically?
and the Hiss case' in Intelligence and National Security (18:3 Autumn 2003) and 'In Re Alger Hiss: A Final Verdict from the Archives of the KGB', in Journal of Cold War Studies (11:3 Summer 2009), the latter forming part of a special issue containing approving assessments of the Vassiliev notebooks.
This is also known as code making, or encryption, as distinguished from cryptanalysis
, also known as code-breaking, or decryption .
